Many companies that sell computer software are trying to increase the productivity of their programmers,
measured by the lines of code written in one day by a programmer. One method attempted by some companies is to let programmers work from home. Programmers who work from home do not need to commute to and from work and can therefore
spend more of the day writing code. Therefore, companies that allow their programmers to work from home will see a corresponding increase in the productivity of those programmers.
Which of the following, if true, most strengthens the argument?
1.Before the advent of virtual private network technology, working outside of the office presented security risks unacceptable to most companies. --
Incorrect, out of scope.
2.Programmers write more effective code when they are able to work in a comfortable environment. --
Incorrect, tricky one. Effectiveness of the code is not mentioned in the passage so eliminate this option.
3.Companies that allow employees to work from home can see reductions in certain expenses, such as electricity and building upkeep. --
Incorrect, out of scope, expenses are not mentioned as a measure of productivity.
4.Most older companies oppose allowing employees to work from home, whereas most newer companies support employees working from home. --
Incorrect, irrelevant comparison.
5.The number of lines of code a programmer writes per hour is relatively constant. --
Correct, though it doesn't seem to be the 'ideal' answer, but it is the best of the lot. As per the argument, programmers will save time by staying at home and the productivity is measured by the lines of codes written so, if the rate of coding is constant then programmers can write more code lines in a day by staying at home.
